Whether you think a case on your phone is good protection or useless bulk, you have to admit there's a huge market for them. Some are sleek and trim, others are bulky but have features like batteries or space for credit cards. This week, we want to know which you think are the best for the iPhone.

The last time we asked you if you used a case, most of you said yes (even though the numbers were pretty split), so now we want to know which ones you use to keep your phone safe from drops and cracked screens, or to add function to your phone that it wouldn't otherwise have. Sadly, because Android devices differ so much in size and shape, there's no set of universal go-to Android cases, so this week's Hive is just for iPhone users—and we know you have plenty to choose from. Let us know your pick in the discussions below.

The call for contenders is closed! To see which of your nominees made the top five, head over to the Five Best iPhone Cases to check out the finalists! Then, make sure to cast a vote for your pick to be the all-out winner!

Hive Five nominations take place in the discussions, where you post your favorite tool for the job. We get hundreds of nominations, so to make your nomination clear, please include it at the top of your post like so: VOTE: BEST IPHONE CASE. Please don't include your vote in a reply to another person. Nominations emailed to us will not be counted. Instead, make your vote and reply separate discussions. After you've made your nomination, let us know what makes it stand out from the competition.

About the Hive Five: The Hive Five feature series asks readers to answer the most frequently asked question we get: "Which tool is the best?" Once a week we'll put out a call for contenders looking for the best solution to a certain problem, then YOU tell us your favorite tools to get the job done. Every weekend, we'll report back with the top five recommendations and give you a chance to vote on which is best. For an example, check out last week's five best digital-to-analog converters (DACs).

The Hive Five is based on reader nominations. As with most Hive Five posts, if your favorite was left out, it's not because we hate it—it's because it didn't get the nominations required in the call for contenders post to make the top five. We understand it's a bit of a popularity contest, but if you have a favorite, we want to hear about it. Have a suggestion for the Hive Five? Send us an email at tips+hivefive@lifehacker.com!
